Fructan

Fructans, also known as fructans, are carbonaceous polysaccharides that are composed of fructose units linked together by glycosidic bonds. This group of compounds makes up a large part of the storage sugar in plants, specifically grasses, onions and garlic. Fructans are unique in that, unlike other polysaccharides, they are directly absorbed into the upper intestine and are not enzymatically hydrolyzed in the small intestine.

Fructans are often used in the food industry, specifically in bakery and confectionery, where they act as natural sweeteners and improve the technological properties of dough. They are also used in the production of beverages, ice cream, yoghurt and other dairy products. Fructans also have prebiotic properties and are therefore often included in probiotic dietary supplements. In addition, fructans are also included in some pet foods as they have an effect on improving the intestinal microflora. Because of these properties, fructans are also often used in cosmetics, specifically in emulsions, creams and face masks, where they promote the formation of healthy skin. In addition, more recently, fructans have begun to be explored for medical applications, particularly for their anti-inflammatory and immunomodulatory effects.
